School children could fall prey to repetitive strain injury (RSI) caused by the misuse and overuse of computers, campaigners have warned.

The RSI Association is concerned that many pupils do not have the correct workstations and equipment to help prevent the condition.

And head teachers have backed their fears, urging the government to give schools better advice on how computers should be used safely in schools, and more money to implement it.

The government has said it wants every school connected to the internet by 2002.

Many pupils now have computers at home

Last year, there was one computer for every 13 primary school pupils, and one for every nine in secondary schools.

But head teachers say that in many schools, investment in computers is running way ahead of provision of the adjustable desks, chairs and
workstations needed for children to use them safely.

In the business world, growing awareness of the dangers - and potential cost - of RSI is prompting employers to take the quality and design of office furniture more seriously.

But campaigners say the issue is barely recognised in schools, where children risk serious damage by using computers while sitting at
traditional desks.

They add that even greater numbers of children may be putting themselves at risk by the way they use computers at home.

Poor posture

Wendy Lawrence, chair of the RSI Association, said: "We are getting more and
more calls from parents who are concerned by the way children are using
computers and video games.

"In schools especially, low chairs that cannot be adjusted for height, plus
tables that may also be too low, combine to produce poor posture and increased risk of developing RSI.

"We need to alert teachers, parents and children to this risk."

Chris Thatcher, president of the National Association of Head Teachers, said: "Awareness of this problem is growing rapidly. Heads need to consider much more than just the numbers of computers they have in their schools, but how the children are using them.

"No-one is really saying to schools; here are 20 computers, now you need 20 proper workstations for children to use them safely.

"The tendency has been to say 'Here are the computers, now get on with it'.

"I would say that most computers being used by children in the home and at school are not being used on proper workstations.

"This is an issue that must be grasped. It is up to the government to give
schools advice on how children should use computers safely, and provide them with the resources to carry it out."
